The Dytran model 3237A2 is an IEPE piezoelectric accelerometer expressly designed to cover most wide-band frequency points of Rotor, Track and Balance (RTB); airframe; helicopter; and fixed wing aircraft. The industry has commonly referred to these sensors as “spark plug type”, due to their similar appearance.

Available with a sensitivity of 25 mV/g, the Dytran model 3237A2 features a hermetically sealed stainless steel construction for use in high humidity and dirty environments, as well as case isolation to avoid EMI/ground loop interference. Units feature an axial mounted military-style 3-pin D38999 connector, 1/4-28 mounting thread and lockwire holes.
